HAND CYLINDER PRINTING-PRESS.

' SPECIFICATION forming part Of Letters Patent NO. 677,910, dated July9, 1901.

Application fi ed December 20,1899- Serial No. 741,043. (No model.)

To all whom it may concern.-

Be it known that I, LESLIE B. Woonaurr, a citizen of the United States,residing at San Miguel, in the county of San Luis Obispo and State ofCalifornia, have invented certain new and useful Improvements in HandCylinder Printing-Presses; and I do hereby declare the following to be afull, clear, and exact description of the invention,such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to that class of hand cylinder printing-presses inwhich the im pression is made by means of a cylinder rolling over a formof type placed upon a fiat bed; and it consists generally in the novelcombination and arrangement of the various parts,

as will be hereinafter more fully described,

v roller in one of its normal positions; Fig. 2,

a side view in perspective, showing the frisket down and theimpression-cylinder in position to makeits travels over the bed; Fig.

3, a similar view showing the frisket down 7 and the impression-cylinderin position to pass under the ink-apron; Fig. 4, also a similar viewshowing the cylinder in its second normal position and the frisket up;Fig. 5, a detail side view of the impression-cylinder and one pair ofthe cables for'controlling it, and

Figs. 6, 7, and 8 are enlarged detail views of the means for raising theimpression-cylinder when the press is to be used as a proof-press.

In the several views the letter A indicates the bed of the press, towhich are firmly bolted the sides B. The upper edge of the sides isprovided with depressions or recesses b"b and their ends with uprightsor standards 11 These uprights are connected together by angularimpression-rails b, which are vertically adjustable by means of thebolts b passing through slots b made in the rails to regulate theimpression of the cylinder 0. This cylinder is covered with felt orother suitable material to present a yielding surface and is mounted ona shaft 0, having a crank c at one end thereof. The cylinder isjournaled between the upper edges of the sides B and theimpression-rails, and its shaft is provided with flangedfriction-rollers 0 one at each end, which run freely upon the upperedges of said sides. The flanges of the rollers prevent lateral movementof the cylinder and.

permit said cylinder to freely rotate as it is caused to move back 'andforth over the bed.

Secured to each end of the impression-cylinder is one end each of a pairof cables D D,

the other end of each pair being secured to the ends of the bed A or thesides B, as shown. A portion of each pair of cables is wound around thecylinder, so that when said cylinder is being rotated in one directionone pair of cables D will be unwinding, while the other pair D will bewinding up on the cylinder, as shown in Fig. 1, to cause its return inthe other or opposite direction. Thus by turning the crank c to theright or to the left the cylinder may be. rotated back and forth overthe impression-bed. I

The letterE indicates the frisket or tympan, upon which is placed thepaper to be printed. It is of the usual form and is hinged to one sideof the bed, as shown in Figs. 1 and 4.

Any suitable ink-distributing apparatus may be employed with my improvedpress,

but such apparatus should be so positioned that the operating-crankthereof will be within easy reach of the person operating the im;pression -cylinder, so that he may read1ly distribute the ink withoutmaterially interfering with the printing operation, thus makingtheoperation of the press practically continuous. distributing rollers tothe face of the type by any well-known means-such, for lnstance, as theordinary hand roller. An ordinary form of inking apparatus is shownattached The ink is conveyed from the inkto the back of the press, inwhich the numeral 1 indicatesone of theink-distributing rollers,

2 the crank for operating the same, and 3.the

- de'r is caused. to rise out of recesses- 12,, as shown-in Fig. 2,,andto, travelover thebeduntil itreaches. the point shown. in Fig, 3,.

, turning. the, crank to the right. apron, Eig. 3,,which coverstherecessb where the impression-cylinden rests, serves as at bridgefonthe-inking-roller to pass from the nkt istiii-buting rollers. to thetype-formsand back. and also serves as a protectionto-the ink-apron.

* The impression-rails hold the impressioncylinder down to thetype-form, and being adjustable a lesser or greater degree of impressionmay be obtained by raising or lowering said rails. i

The press may be mounted upon any suitable base or support of convenientheight, such as the framework shown in the drawings, which consists ofthe side supports 4 4 and the base 5, strengthened by the braces 6 6, orit may be supported upon a table of proper height for convenience inworking.

The operation ofthe press will be-readily understood fromthe foregoing.description without further explanation other than to state, that. the;impression cylinder hastwo normalpositions of rest--one,in therecessesb, as shown 1n. F1g. 1,.and the other in recesses=b' ,.as.showniriFig. 4 The-cylinder vwhen-in.neither of these positions-of rest isout of theway when inking. the forms-orputting; thereon or taking, themoff. of the-press. By turning; the crank c to the left the cylinwhenitwill pass under the ink-apron and dropinto recessesb-,,asshown in Fig.4; The frisketis thenthrown up, the printed sheet removed, a. blankvsheet adjusted, thefrisket thrown down, and the operation repeatedbySaid inkimpression; cylinder. Theink.- apronis so hinged toltheframe of.the pressthatwhen the cylinder is. underneath it' the movement ofthelcylinder upward wilL raiseit up until. thecyIihden hasmoved out ofthe way,,' whe.n the apron willdrop back. into. place. When the cylinderis returning toward-the apron, it

passesunder. and engages: an armattached I to. ne endof saidapron andwhichis-so adus edthatwhen the cylinder haspassed. be-

neath arm 3" and reached therecess the-apron will havebeen. raised a.snlficient height to allow. thecylind'er to passunder into itspositiomof rest,.w.hen the, apron, will drop into tsnormal position.

each end of the impression-rails, two.being shown in. Fig, 6. provided.with a. square orjack screw head by. means of whichLi't. may be adjustedand;

,The depressions g are of less depth than the depressions 9 theformerbeing of a depth j 11st sufficient to engage with the lug g and preventthe hand-wheel from turning, while the latter is of a depth sufficientto permit said lug to enter its full length. The vary .ing depths ofthese depressions serve to compensate for the thickness of the bottomsof the galleys from which proofs are to be taken, so that when the lugisin the depressions g -the impression-rails will be forced down, as;shown by the separation between the wheelhubs and rail-washers g.,giving,the requisite lpressure for the type-forms on-thc pressbed; fbutwhen the lugisrin the depress-iong there iwillbeno separation betweenthe wheel-hubs .iand railwashers,. asshown.in.

E'lhe hand-wheels are only operated to allowtheir lugsfto-ongage either of the depressions jg or 9. andv theyin-nowise-interfere wit-lithe gproper adjustment of the impression screws,gas they act independently thereof. The imipression-screws may besecurely held in their ad'justedposit-ion by the use of jam-nnts orQbinding-screws, if desired, to prevent accie i-dental turning. I

Various modifications in the construction .and arrangement of thevarious parts of my ,Einiproved press may be made without depart- ;ingfrom the spirit of my invention or sacri- I i fi-cing the principlethereof.
